To all whOm it may concern Be it known that I, FRED P. HoUsER, citizenof the United States, residing at Bully Hill, in the county of Venangoand State of Pennsylvania, have invented certain new and usefulImprovements in Motor-Car-Actuated Power-Jacks, of which the followingis a specification.

The object, construction and utility of my improved motor-car-actuatedpower jack, are herein set forth with suflicient clearness to enablethose skilled in the art to which it most nearly relates, to make anduse the same.

The object of this appliance is to provide means whereby a motor-car maybe quickly and easily made available as a power plant, for the operationof various machinery, and more especially for such machinery as isusually employed about a farm, such as threshing machines, feed cutters,wood saws, pumps, etc.

The construction of my improved powerjack is clearly shown in thedrawings which form a part hereof, the figures of which are as follows:

Figure 1 is a plan view of said jack. Fig. 2 is a side elevation ofsame, one of the frictional transmission pulleys being removed to exposeother parts to view.

The'construction as here illustrated is substantially as follows: Iprovide a base which consists of two main members 1, 1, that arearranged parallel to each other, and positioned at a distance apart thatis somewhat less than the distance between the rear wheels of anautomobile: Said two members are secured together in any suitable way,as by the cross-pieces 2, 2. Extending upwardly from said members 1, andsecured rigidly to each thereof, is an upright standard or member 3, 3;the height of said standards is somewhat greater than the height of therear axle of an automobile, from the ground or floor-line. Pivotallyattached to each of said standards is a jack-lever, 4c, 4; the shorterend of each of said levers is arranged to be placed beneath the axle ofan automobile, when said ends are lowered so as to pass beneath saidaxle; then, by lowering the opposite, or handle end of said levers, saidrear axle is raised so that the rear wheels 5 are free from the groundor floor, and are free to revolve: Said levers 4 are retained in theoperative position, as shown Specification of Letters Patent.

Application filed April 10, 1916. Serial No. 90,211.

in Fig. 2, by the hooks 7, which engage the handle ends of said levers.Mounted upon each of the base-members 1, is a verticallyextending stand8, which stands are each pivotally connected at its lower end to itsrespective base member in such a manner that the upper end of each ofsaid stands is free to swing toward or away from the axle 6,the outerposition of said stands being shown by dotted lines. Each of saidstandards carries, in proximity to its upper end, a bearing or box 9 forthe shaft 9 which extends across the frame and upon the outer ends ofwhich shaft, friction pulleys 10, 10, are rigidly mounted or keyed tosaid shaft; said friction pulleys are adapted to be moved intofrictional engagement with the wheels 5, whereby said pulleys are causedto revolve and to drive said shaft 9. Upon said shaft 9 is also mounteda belt-pulley 11, from which power may be transmitted by means of a beltto any machinery that is adapted to be so operated. For the purpose ofimparting to said stand 8 said swinging movement which actuates thepulleys 10 into frictional engagement with the wheels 5 of the motorcar, I provide the following means: Attached to the upper end of each ofsaid stands is a chain 12, or any other suitable flexible element, whichis adapted to be passed around the axle 6 of the motor car, the free endof said chain is then brought back and engaged by the hook 13, that iscarried by a lever 14, when said lever is thrown upward to the positionindicated by the dotted line 15; then, when said lever is moved downwardto the position shown, said stand 8 is caused to move inwardly, and thepulleys 10 are thus caused to bear, with the required degree of pressureagainst said wheels 5 of the motor car, whereby motion is transmitted tosaid pulleys and to their shaft 9 and the belt-pulley 11.

It will be readily noticed from an inspection of Fig. 1 that the lever14 is a portion of a continuous rod which is carried by and extendsacross said stand, and is provided with a chain-actuating member 14: atthe side of said stand opposite to the member 14: By this arrangement,both of said pulleys 10 are caused to bear with an equal pressure uponthe respective wheel by which it is driven.

I claim the following:

A motor-car-aetuated power jack com- 10 adapted to actuate said standinto said operative position and to retain the same therein as desired,and a belt-pulley rigidly mounted upon said shaft.

In testimony whereof I afiix my signature in presence of two Witnesses.
